I've seen people post some pretty crappy stuff on facebook about other people. One guy went ballistic on his gf for walking out after 7 years. He was a former roommate of my ex. This guy was a raving loon who got into fist fights at AA meetings. When I read everything he had to say about her. All I thought was how did she do 7 years of this whack job? He looked like crap, not her.
You are hurting and that's normal, but you will heal and some day be a happy and grateful member of the "bullet dodgers society" which I just made up! Now go out and do something that has nothing even remotely to do with him! (((Hugs)))
